Ahhh, tink, it was not saying 'unknown host/location'. It knew where to connect, just wasn't allowed to. Plus, adding localhost to xhost + is not that great a risk because only someone logged into localhost can connect to it. (If they had ssh/rsh, etc access, they would redirect to their local machine, which is a whole nother ball of wax).
I would agree that ssh is more secure, but did not want to overwhelm the poster. Besides, if the xhost + localhost
didn't work, with a new error, then I would get into export DISPLAY, etc.
